Three forces acting on an object are given by F1 = (−1.85 i + 7.35 j) N, F2 = (4.70 i − 1.15 j) N, and F3 = (−45.5 i) N. The object experiences an acceleration of magnitude 3.70 m/s2.
(a) What is the direction of the acceleration?
(degrees counterclockwise from the positive x axis)
(b) What is the mass of the object in kg?
(c) If the object is initially at rest, what is its speed after 16.0 s in m/s?
(d) What are the velocity components of the object after 16.0 s in m/s?

F1 = (-1.85 i + 7.35 j) N,
F2 = (4.70 i - 1.15 j) N,
F3 = (-45.5 i) N.

Net force,
Fnet = F1 + F2 + F3
= (-1.85 i + 7.35 j) + (4.70 i - 1.15 j) + (-45.5 i)
= (-1.85 + 4.70 - 45.5)i + (7.35 - 1.15)j
